Oviedo is the former Leo Nunez, who finished 142 games for the Marlins from 2009-2011. The 30-year-old was disciplined for identity fraud prior to last season and appeared in just three minor league games before an elbow injury requiring Tommy John surgery ended his campaign. For his career, Oviedo has a 4.34 ERA with 7.3 K/9 and 2.9 BB/9 across seven big league seasons.

Because his injury will likely cost him the bulk of the 2013 season, the Rays' deal with Oviedo includes an option for 2014, Topkin tweets.

Duncan, 33, spent much of the season as Cleveland's left fielder and posted a .203/.288/.388 batting line in 264 MLB plate appearances. The left fielder/first baseman refused a minor league assignment in October, making him a free agent.

Wright, 38, has 17 major league seasons to his credit. The veteran spent 2012 with the Dodgers and made 66 relief appearances, posting a 3.72 ERA with 7.2 K/9 and 4.0 BB/9. Sandoval, 32, had a 2.97 ERA with 7.4 K/9 and 2.8 BB/9 in the Mexican League last season.
